Try this,

  1. Change your 'HrqQuestions' as array
  2. Group your questions using 'id'
  3. And repeat values of grouped questions. Like this,

angular.module('app',['angular.filter']).controller('MainController', function($scope) {
  $scope.HrqQuestions = [
      {Answer:"White",AnswerID:967,answer_type:"RADIO",fullquestion:"Your Race",id:6},
      {Answer:"African American",AnswerID:968,answer_type:"RADIO",fullquestion:"Your Race",id:6},
      {Answer:"Asian",AnswerID:969,answer_type:"RADIO",fullquestion:"Your Race",id:6}
<!DOCTYPE html>
<html ng-app="app">
<script src=""></script>
  <script src="//"></script>

<body ng-controller="MainController">
  <div ng-repeat="(key, value) in HrqQuestions | groupBy: 'id'">
    <div><strong>Id:</strong> {{ key }}</div>
     <p ng-repeat="v in value">
       <strong>Answer {{ $index + 1}}</strong>. {{ v.Answer }}
